edk2/MdeModulePkg/Bus/Pci/XhciDxe/XhciSched.c: lines 2784-2791
-----------
if (DeviceSpeed == EFI_USB_SPEED_SUPER) {
//
// 6.2.3.4, shall be set to the value defined in the bMaxBurst field of
the SuperSpeed Endpoint Companion Descriptor.
//
InputContext->EP[Dci-1].MaxBurstSize = 0x0;
} else {
InputContext->EP[Dci-1].MaxBurstSize = 0x0;
}
